Reflectivity of Some Materials; at 94 GHz

Abstract

In order to better understand the characteristics of discrete natural land clutter at millimeter wavelengths, an experimental investigation of the relative reflectivity of various materials at 94 GHz was performed using a substitution technique. The data show that nonconducting materials have a relative reflectivity on the order of 2-3%, and that absorbed water can increase the relative reflectivity significantly.
